To improve interagency coordination, which ICS application is used when multiple agencies have jurisdiction over a single incident?

• A. Unified Command
• B. Joint Information System
• C. Emergency Operations Center
• D. Incident Command System

Answer: (B)

Unified Command is the arrangement used when more than one agency has jurisdiction over the same incident. It lets each agency retain its authority while operating under a single, integrated command structure, sharing objectives and the incident action plan. This approach prevents conflicting directions and ensures coordinated resource assignment and information flow among all involved agencies. The Joint Information System, by contrast, focuses on coordinating public information and media messaging, not on the on-scene command or interagency decision-making. The Emergency Operations Center is a centralized location for strategic coordination, but it doesn’t define how field-level command is shared among multiple jurisdictions. The Incident Command System provides the overall framework, but Unified Command specifically addresses multiagency, joint command on a single incident.
